    Prevent Mount/Umount operation being available for LUKS (#760080)
    
    The code currently allows attempting to mount and unmount a LUKS
    partition.  It is nonsense to directly try to mount and unmount a LUKS
    partition and obviously doesn't work.  For read-only LUKS support there
    is no need to attempt to apply this to the encrypted file system within.
    Therefore prevent these operations for LUKS partitions.
    
    Bug 760080 - Implement read-only LUKS support
